Browser Extension FAQ
What is Manifest V3, and why is it critical for our browser extension?
Manifest V3 is Google’s latest, most secure browser extension platform. It introduces fundamental changes to privacy, security, and performance. We build all extensions using Manifest V3 to ensure they are future-proof, high-performance, and fully compliant with the latest Google Chrome Web Store mandates.
Can an extension securely interact with our internal business dashboards?
Absolutely. Browser extensions are powerful tools for technical workflow augmentation. We can build secure extensions that 'read' data from your internal CRM or third-party SaaS tools and provide one-click actions, automated data entry, or custom strategic reporting directly within the user’s active tab.
Do you manage the entire Chrome Web Store submission and review process?
Yes. We manage the complete lifecycle—including developer account preparation, privacy policy drafting, and justifying permission requests to Google. We manage all technical communication with the Google review team until your extension is successfully published and live.
How do you ensure the extension doesn’t slow down the browser experience?
We use 'Event-based' service workers and minimize background script execution to ensure zero impact on browser speed. We optimize content scripts to only execute on necessary URLs, ensuring your users’ browsing experience remains snappy, efficient, and uninterrupted.
Can you build extensions for browsers other than Google Chrome?
Yes. We leverage the WebExtensions API, allowing us to build cross-browser extensions that work seamlessly on Chrome, Firefox, Microsoft Edge, and Brave with minimal code variations, effectively maximizing your reach across all major global desktop browser users.
Chrome extension development involves two distinct contexts that beginners consistently confuse: the content script (runs in the page, can read and modify DOM but has limited API access) and the service worker/background script (runs in isolation, handles extension logic, storage, and network requests). Most Chrome extension projects fail because developers mix business logic between these two contexts, which breaks in Manifest V3 (the current extension standard that replaced V2 in 2023). A Chrome extension in India costs ₹50,000–₹5 lakh: a simple page modifier or data extractor costs ₹50,000–₹1.5 lakh, while an extension that integrates a custom backend API, handles OAuth, and manages sync across devices costs ₹2–₹5 lakh.
By the numbers
Chrome extension development cost in India — ₹50k–₹1.5 lakh for a page modifier, data extractor, or simple productivity tool; ₹2–₹5 lakh for an extension with a custom backend API, OAuth authentication, cross-device sync, and Chrome Web Store publication support

| Extension type | Technical scope | India cost |
|---|---|---|
| Page modifier / injector | Content script that reads or modifies DOM on specific pages — no backend, no auth. Examples: custom UI overlays, data highlighters, form autofill | ₹50,000–₹1 lakh |
| Data extractor / scraper | Content script reads page data, service worker processes and stores it. Examples: price trackers, lead capture from LinkedIn, CRM data entry automation | ₹80,000–₹2 lakh |
| Productivity tool with popup UI | React or vanilla JS popup, background service worker, Chrome storage sync for settings. Examples: tab managers, note-takers, reading list tools | ₹1–₹2.5 lakh |
| Extension with custom backend API | Content script + service worker + Node.js or Python backend + database. Examples: AI writing assistants, SEO analysis tools, CRM integrations | ₹2–₹4 lakh |
| Enterprise extension with OAuth + SSO | OAuth 2.0 flow, user accounts, cross-device sync, enterprise management (chrome.enterprise API), Chrome Web Store paid distribution | ₹3–₹5 lakh |
Manifest V3 changed the Chrome extension architecture in ways that break most V2 patterns — persistent background pages are gone, replaced by service workers that terminate when idle. An extension built by a developer who does not know this difference will fail intermittently in ways that are very difficult to debug.
